To all whom it may Concern:

Beit known that I, CHARLES WV.y Srnn'xnn,

and

Allegheny and State of Pennsylvania, have invented a new and yuseful Improvement in f Axle-Bearings, of `which the following is a specification. v

My invention relates to axle bearings for electric railway motors, and it has for its object to provide an axle bearing that is particularly simple and inexpensive 1n construction. n

Another object of my invention is to provide means for preventing the entrance of dust and dirt into the axle bearing, by the use of a guard member that maybe readily A applied to the bearing.

Axle bearings of usual construction 'for electric railway motorscomprise cylindrical bearing members composed ofsome suitable bearing material or` .babbitt-lined `metal,

shells. Such bearing members are `usually positioned in suitable housings, and the bearthe plates v flange 10' of the bearing shell portion 8. The t closely around the por ing surfaces are protected from the entrance of dust and dirt by the use of guard mem.-

. bers encircling the axles and suitably secured views showing modifications A (not tion 2, a portion 3 of somewhat greater'diam- 2, and a wheelseat 4 to the bea-ring housings..

By my invention,-I provide an axle bearformed -1 and is provided Vwith an.

ing in which the bearing shell is from pressed metal integral flange to which the dust guard may be secured, so that thetwo members form a substantially unitary structure.

In the accompanying is a view, in end levation, of an axle bearing and guard member constructed in accordance with my invention. Fig. 2 is a sectional view along the linen-+11 of .,Fig. 1, and Figs.; 3 and 4 are fragmentary sectional of the'parts shown in Fig. 2. L

An axle 1 of an electric railway motor shown) is provided with. ajournal poreter than the journal provided with a keyWay 'by means of which a suitable vehicle wheel may bev mounted thereon. The journal portion .2 of the axle 1 isrotatablyinounted in a bearingl 6 that i-s located within the bore of a bearinghousing '.port 24 by means of rivets 25,

y 7 The bearing 6 comprises two similar drawings, Figure 1 outer flange 19 of the ',cured to the f lange'9 of by .means of rivets 22.

preferably annular flanges 9 and 10. A layer 11 of Babbitt metal is cast into eachshell portion- 8 and extends around the outer face of the inner flange 9. One of the shell portions 8 is further provided withv a plurality/' of,

drilled openings- 12 extending-'through the flange 97 and the completed bearing half is tially equal to the outside diameter of the la-yer 11 of Babbitt metal that is formed upon the flanges -9fofthe Ashell portions 8.

Guard members 15 severally comprise a pair of semi-.annular plates 16 between which ar included layers '17 of felt or some other similar material. The inner diameter of the plates 16 is slightly greater than the diams. eterv of the portion`3. of the vaxle 1. Each guard vmember 15 is held together and maintained lc'oncentrically with respect to the axle 1 by'means of rivets 16a extending through 1-6 and Vlayers 17 and the outer layers 17 of felt tion 3 of the axle U of any dust or dirt into the ad]acen`t bearing surfaces.

guard members 15 are maintained COIIGGIltI'- cally with respectto' thev axle lsby means o semi-annular supporting members 18 that are of substantiallyv Each guard member 15 is secured to the support 18 by means of rivets 20, and 'the inner flange 21 is seth'ershell portion 8 A further modification of my invention l.is shown inv Flg. 4 wherein a semi-annular strip -23 is welded tothe iange 9 vof eachv shell portion 8. The guard members 15 are main tai-ned concentrically with respect to the axle 1 by means of semi-annular supportmg menibers -24 that are of substantially L-shape'jin Z-shape in cross section.

fcross section.: -Each guard member 15 Iis.,

secured to a transverse portion of the sup'- and the longitudinal portion of thesupport 24 1s secured to the lstrip 23 .by means of set screws 26.

vF rom the foregoing, it is lapp-arent that an axle bearin`g and a dust guard constructed in accordance with my invention constitute a substantially unitary structure, the use of which is adapted to effect a saving of j both labor and material in the construction of electric railway motors.

While I haveshwn my invention in-its simplest and .preferred forms, it is not S0 limited but is susceptible of various other 1 cal seat, a bearingmember positioned there-- in and provided with aplurality of external and concentric flanges, and an axle rota- .tably mounted in the said bearing and having an enlarged portion adjacent to .the 1nl 'ner flange, of a guard member encircling thev enlarged portion of the said axle and secured tothe outer of the said flanges, and a layer of` 'bearing metal positioned within sald bearing member, a portion of which is disposed between said bearing member and the enlarged portion of the shaft.

4'. In an axle bearing, the combination with a housing member having a cylindrical seat, a bearing member positioned therein and comprising a pressed metal shell provided with an inner layer of bearing metal, and an axle rotatably mounted in the said bearing, of a guard member encircling the said-axle and secured to the said shell.

5. In an axle bearing, the combination with a housing member having a cylindrical seat, -a bearing member positioned there- 2. In an axle bearing, ithe combination guard member encircling the said axle and y secured to the flange of the vsaid shell.

tion of non-bearing metal provided with a layer of bearing metal, of a guard member secured to said non-bearing-metal portion. 'I

`9. I1 a bearing, the combination wlth a ing metal positioned within said bearing. member and provided with a flange, an 4axle rotatably mounted in the bearing and having an enlarged portion adjacentto the inner,of the said bearing member fianges, of a guard member secured to the outer bearlng-meinber flange, the bearing-metal flange belng interposed and having then-ange of layer of bearing metal interposed between the said bearing member and the said ven'- larged portion of the shaft. s

11. In an axle bearing, a housing member having a cylindrical seat, .a bearing member positioned therein and provided 'with two external flanges, metal positioned within said bearing member and provided with a flange, an axle rotatably mounted' in the bearing and having an enlarged portion engaging one side ofl the bearing-metal fiange,l and a guard member encircling the enlarged portion of thefsaid' a layer of' .bearing lportion of non-bearing metal provided with In testimony whereof, I have hereuntov subscribed my name this 31st day of Aug. 1915.
